5The distribution patterns of rare earth element compositions in the hydrothermal components are similar to that of pacific seawater. This infers the complex and significant interactions of hydrothermal fluid with surrounding seawater during its diffusing process. Dissolved trace metals in the hydrothermal fluid can be removed by settling terrigenous or biogenic particulates and precipitated quickly from the hydrothermal plume round the vent. On the other hand, hydrothermal particulates would also scavenge some elements from the seawater to coprecipitate into the sediments.

5岩芯沉积物中热液源组分携带的稀土元素组成具有类似海水的分布模式，反映了热液流体喷出海底后与其它物源物质之间的复杂的相互作用：一方面大量生物和陆源碎屑物质的快速沉积导致溶解态的热液源物质被快速清扫，无法向外扩散，快速堆积在热液喷口附近；另一方面，随热液羽状体向外扩散的颗粒态热液源物质也清扫海水中的元素共同进入沉积物。
